Water quality. Detection and enumeration of bacteriophages - Enumeration of bacteriophages infecting <i>Bacteriodes fragilis</i> Ingestion-build-79769 New preferred requirement for digital1 Scope This part of ISO 10705 specifies a method for the detection and enumeration of bacteriophages infecting Bacteroides fragilis by incubating the sample with an appropriate host strain. The method is applicable to all kinds of water, sediments and sludge extracts, where necessary after dilution. In the case of low phage numbers, a pre concentration step may be necessary for which a separate International Standard has been developed. The method is
